Window Object Method Example
Example 1: We’ll use the window.alert method in this example to show how it works:
// This is window.alert method
console.log(window.alert("w3wiki"))
Output:
Example 2: In this example, we’ll use the setInterval() Method:
<!DOCTYPE html>
<html>
<body>
<h2>The setInterval() Method</h2>
<p id="demo"></p>
<script>
const element = document.getElementById("demo");
setInterval(function () {
element.innerHTML += "w3wiki</br>"
}, 500);
</script>
</body>
</html>
Output:
